I modified a .po file, basically I opened as txt file and made the changes, however I uploaded it and is changes are not working.
I wonder if I need an special software for doing and generate a new .mo each time I make a change, or what am I missing?
Thank in advanced
You need to do "msgfmt" using the command line tool to convert the .po to a .mo, that is what Wordpress (and all gettext compliant software) uses.
http://codex.wordpress.org/Translating_WordPress suggests various tools including http://www.poedit.net/ which I found made editing plugin language files a lot easier...
If you are using windows you can use Poedit to edit this files and generate .MO files.
If you want to translate the best way is by creating a new "Catalog", with te correct name. Generating new files (i.e: pt_BR.po & pt_BR.mo), and keeping the original file.
